Be it known that I, ERNST Wiss, a subject of the `German Emperor, and residingV ait Griesheim-on-the-Ma1n, Germany, have invented certain new and useful Improvements in Devices'for SeveringMetal Bodies,

This invention relates tolapparatus for severingmetals by means ofa flame assisted by a jet of oxygen.

I will describe this inventionwith reference to the accompanying drawing, Figures l and 2 being elevations at rightangles' to` each other. y lThe apparatus is provided with two nozzles, through one of which (that marked a) forms the heating medium, while through the .other nozzle b issues a jet of oxygen. The said nozzlesk converge toward each other and it is essential that they beso arranged;4 as to form an acute angle (littering as'much as possible from a right angle, consistent with the longitudinal axes ofthe jets intersecting each otherat the edge c of the metal to be acted. upon, as otherwise the gas cur rents from the respective nozzles would blow each other aside and .detract from thel sharpness of the jet of oxygen, as is the case'pwhen the nozzles form with each other a right In the arrangement accordingto` this ingases are so arranged and supported in relation-to the material to be' acted' upon that the face of the material is at the'meeting point of jets which are brought togetherat. an acute angle, whichpoint'is th Lhottestpart of the heating llame so that the actions of the heating flame and of the jet of oxygen As it is necessary to vary the sizeof the heating flame in accordance with the iece to be severed 'provisionfshould 'be ma'ein order `that when the dame becomes larger,

This result can be obtained for example by arranging c i the oxygen nozzle slidably in, or on an arm Z attached'to the tube forthe heating llame. e is an axle common to both nozzles','the saidaxis being arranged so that it lies in the line which bisects the angle formed-by the two nozzles. `The said 'axle e carries guiding ,rollers f which enable the nozzle arrange- Application led January I5, 1907.

ylment to be guided on the piece of work so 4 be cut. If the nozzles are not arranged in this particular relation the stream of oxygen will extinguish the heating flame. By arranging the nozzles inthe relation described `it will be seen that the line or planeof cut through the bodyacted upon will be substantially equidistant from the lines or planes 'of the nozzles at all depths. That is,

the relation between the jets delivered through the nozzles on the surface acted f upon will be thesa-ine at every stage in the 'cutting operation. v

Having now particularly descrlbed and ascertained the nature of my said invention A and in what manner the same is to -be performed, I declare that what I claim isz- 1. The combination in an apparatus of the character-described of two nozzles and a support therefor adapted' to bear on and support thenozzles in proper relation to the face of the article to be out, said nozzles arranged at an acute angle on the su port to insure the meeting at said acute ang eof the gas jets at the tace of the material, and maintainv the same relation' between the jets throughout the cutting operation.

' 2. The combination in an apparatus for severing metals,'of separated parallel wheels axially in line-and two nozzles arranged at 'equal angles on opposite sides ofthe said axis, converging at their lower ends to bringthe jets therefrom together at the plane sup- 'ico portin Ithe wheels, and means for supplying di erent gases to the two nozzles.
